Trajes Fatais: Suits of Fate sprites

[Macaulyn]

So, I was trying to rip sprites from this game called Trajes Fatais: Suits of Fate, a game on Steam that has been in development hell for a long ass time. I tried multiple asset ripping tools, but though I can get some sprites (some portraits, tutorial stuff, lifebars), I can't get the most interesting part: the characters and their specials. There is a folder called "Animations" in which there are folders for each character, with those having around 300 files each, so those could be the key to getting the sprites, assuming each file isn't a sprite itself. Problem is, the files inside have a fake extension, .trafAnimation (TRAF used to be an acronym for the game) and I have no idea what is the original extension of these files were, is there any way to discover a file's original extension? How can I rip those?
